4x + 2y = 0
2y = -4x
y = -2x...the slope here is -2
the above line ^^ is parallel to y = -2x + 3.....because parallel lines will have the same slope
<span>6x-3y=27 --> 3*(2x-y = 9)
3x-y=13 Doesn't factor</span>
Answer:
1/10 or 10%
Step-by-step explanation:
First, you add up all the quarters to get the total amount of possibilities for the first quarter that gets pulled out.
4 NY + 3 PA + 3 VI = 10 total quarters.
So the total number of quarters becomes the denominator for the first probability, and the total number of PA quarters becomes the numerator.
So the probability of Jim pulling out a PA quarter first is 3/10.
Now you have to find the probability of drawing a VI quarter as the second quarter. Since it's known that Jim would have already pulled 1 quarter out, that means the total number of quarters he could draw is now 9, so 9 would be the denominator of the second probability. Since there should be 3 VI quarters left still in his pocket, the numerator for the second probability is 3.
So the probability of Jim pulling out a VI quarter second is 3/9.
Now to get the final probability of Jim pulling out both a PA quarter and a VI quarter in the correct order, all you have to do is multiply the two probabilities together and then you should get the probability of the correct quarters being pulled out inn the correct order.
The first probability, 3/10, times the second probability, 3/9 equals the total probability of 9/90, and it simplifies to 1/10 or 10%
1. The coefficient of the squared term (-1/3) is negative, so the graph opens downward.
2. Matching the pattern to
.. y = a(x -h)^2 +k
we find (h, k) = (-2, 5) . . . . . . selection C
3. See the previous answer. The axis of symmetry is
.. x = h
Since h = -2, the axis is x = -2. . . . . . selection B
